Gan, it would be good to give accupunture a try because it is known to improve lining, blood circulation as well as warms the womb. Personally,I feel accupuncture has help me BFP as previous cycles without accupuncture didnt even lead to any implantation. I am with Dr Zou AMK and will start my accupuncture twice a week after my menses clear. Don't worry about the pain level, Dr Zou is very fast when inserting the fine needles and I believed if we can overcome ivf injections, these should be ok. Dr Zou is a very encouraging lady and is very familar with the IVF procedures. TCM maybe one way of increasing IVF chances and there are many other factors that leads to BFP, but there is no harm trying.
Btw, Dr Loh added baby aspirin on my FET, known to improve blood circulation. Wish u all the best in your FET.
